Christian Eberle is a Contributing Editor for Tom's Hardware US. Input lag Features & Aesthetics There are again varying levels of trailing behind the UFOs due to weaknesses in pixel responsiveness, but this takes a different form to at 60Hz. TN models show obvious saturation shifts vertically. It still provides useful visual demonstrations and explanations which help reinforce some of the key points raised in the written piece. Worth looking at analytic reviews for settings adjustment to colour/refresh rates etc. . Compared to at 60Hz, or indeed a 60Hz monitor, youre getting up to 4 times as much visual information pumped out every second. Nvidia Adaptive-Sync (G-SYNC Compatible) There is a bit of backlight bleeding on the edges of the Alienware AW2521HFs screen which adds some light clouding in an all-black image. The screen surface was a touch on the grainy side when viewing lighter content, although this wasnt a strong layered graininess or excessively sandy appearance thankfully. window.__mirage2 = {petok:"zg2cYY5zq25POHOP6IsDfN8FBZJHLm773fg_fBtMlJU-1800-0"}; The better option is to raise the refresh rate and thats exactly what the Alienware AW2521H does. RtN on 03/03/2023 - 16:22 Still there are some weaker IPS performers out there in that respect. The bottom trim is 15mm wide and features the Alienware logo and a label proudly announcing 360 Hz. A tiny LED at the lower right glows white and doubles as the power button. Responsiveness in games and movies And additional overdrive artifacts with parts of the UFO appearing displaced or over-aliased. One of the most important concepts raised in that article is perceived blur, contributed to by the movement of your eyes as you track motion on the screen as well as pixel responsiveness. The video below shows the Lagom text test, a mixed desktop background, game scene and dark desktop background from a variety of viewing angles. The IPS-type panel of the Dell Alienware certainly provided a key contrast advantage over VA and TN models, though. Motion is the most important performance metric for a 360Hz monitor, though, so the response time needs to be low to avoid ghosting. As noted earlier, AMD FreeSync makes use of Adaptive-Sync technology on a compatible monitor. Performance on the black level test was good overall. The full capabilities of the monitor including 1920 x 1080 @240Hz and Adaptive-Sync for AMD FreeSync can be leveraged via DP 1.2 or HDMI 2.0. As frame rate dropped further, well below 200fps, the connected feel and perceived blur was noticeably impacted. Where possible, the monitor dynamically adjusts its refresh rate so that it matches the frame rate being outputted by the GPU. Note that if the monitor is running at a refresh rate from the first list, including 60Hz, steps must be taken to, Note that 120Hz is listed as a PC resolution, rather than in the Ultra HD, HD, SD list. //]]> In this case appropriate richness and saturation was maintained throughout. This figure is influenced both by the element of input lag you see (pixel responsiveness) and the element you feel (signal delay). There are some further customisable AlienFX RGB LED features an alien motif towards the top left and a large oval running along the inside of the stand neck. The monitor offers fairly comprehensive sRGB coverage (99%), with a very small amount of under-coverage. The curves and flow of the Alienware AW2521HFs make it a bit chunkier than similar monitors, so you have to consider your desk space before buying this model. Dark areas with just a few point sources of light illuminating are common on this title, including dark tombs and passageways. Wed describe the image as rich and natural, with a richness maintained throughout the screen thanks to the strong colour-consistency. Reasonable contrast, in-line with expectation, strong gamma consistency and a pleasing luminance adjustment range This indicates a low viewing angle dependency to the gamma curve of the monitor, typical for an IPS-type panel. At 60Hz, above, the UFO appears soft without sharp focus or clear internal detailing. The USB port to the left, as viewed from the rear, supports fast-charging. As an Amazon Associate I earn from qualifying purchases made using the below link. But far from poor. This is exactly what the Dell Alienware AW2521HF delivered. The red block appeared a fairly rich red throughout. Colour gamut 'Test Settings' Its possible newer Nvidia GPUs, including their RTX series, support this expanded range or it may have just been misreported on the website. Bracketed numbers in our analysis refer to shades on the printed sheet or right side of the screen if theyre ordered consecutively from top left to bottom right. With VSync on the frame rate will not be allowed to rise above 240fps, at which point VSync activates and imposes the usual associated latency penalty. The monitor can also be set to 120Hz although not documented in this testing, results were very much comparable to 144Hz. This is an alternative to VSync which allows the frame rate to rise above the refresh rate (no VSync latency penalty) whilst potentially keeping the experience free from tearing or juddering. Further information on supporting our work. Together, the monitor certainly didnt provide a deep and atmospheric look to dark scenes and is more suited to viewing in a well-lit room. In this case, overshoot (inverse ghosting) including some colourful bright halo trailing due to aggressive pixel overdrive. It has three modes, and Mode 0 is the most responsive. Considering a broader range of pixel transitions, all Response Time settings were fairly similar at 240Hz with Adaptive-Sync in use (VRR on). Some shades, such as cerulean (2) and lilac (8), appear somewhat undersaturated. We refer to these as interlace pattern artifacts but some users refer to them as inversion artifacts and others as scan lines. Created with right-handed gamers in mind, the new Alienware Wireless Gaming Mouse (AW620M) prioritizes comfort, precision and accuracy, featuring our leading-edge sensor technology and patent-pending magnetic-force L/R keyplates. Full HD Monitor IPS *FOR PARTS* at the best online prices at eBay! Its again important to note that individual unit vary when it comes to uniformity and that deviation beyond the measured points can be expected. The refresh rate was set to 240Hz in Windows, although this didnt significantly affect the values or observations on this table. Make sure this is selected (it should be if youve set everything up correctly in Set up G-SYNC). Around 1000:1 even following adjustments to our Test Settings. No additional monitor drivers or ICC profiles were specifically loaded for the review. //]]> Laras skin also appeared much as it should, without the overly tanned appearance that a wider gamut would provide. No saturation losses towards the bottom or edges as youd see from other panel types. 237fps) instead, avoiding any VSync latency penalty at frame rates near the ceiling of operation or tearing from frame rates rising above the refresh rate. The article also covers a technique called pursuit photography, using a moving rather than stationary camera to capture motion in a way that reflects both elements of perceived blur. The numbered Game presets could also be used as a base as they offer the same flexibility. We benchmark 25" Dell Alienware AW2521HF gaming monitor performance in terms of response time, total input lag and display brightness and contrast. Screen Size: 25 inches. The contrast gradients were displayed well, with distinct brightness steps in most cases. Select Manage 3D Settings under 3D Settings. The AW2521HFL is also available, differing only due to this dark grey shade being replaced with a much lighter Lunar Light shade. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks. Luckily, two of the USB ports and the headphone jack are under the panel edge in a more accessible position. Performance on the black level test was good overall. Both our responsiveness article and the G-SYNC article linked to explore the importance of these two elements being synchronised. It was free from the sort of shifts in perceived gamma that can significantly mask dark detail in some regions of the screen whilst revealing too much detail elsewhere. Brighter elements stood out well against darker surroundings, complete with a bit of graininess from the screen surface but nothing extreme. Our RX 580 is far from a powerhouse of a graphics card, so maintaining 240fps was very tricky. You should then ensure that the first slider, Radeon FreeSync is set to Enabled as shown below. This configures it globally, but if you wish to configure it for individual games click Game Graphics towards the top right. The refresh rate was put to very good use overall; fairly strong pixel responsiveness, low input lag and no noticeable overshoot. Aside from for our Test Settings, where various adjustments were made, assume factory defaults were used. On TN models you have things looking far too masked higher up the screen due to high perceived gamma. It looks good on the https://www.testufo.com/ghosting, but when I enter CS:GO, Valorant, or any other games it just looks really bad. Rather than simply reflecting the pixel response elements. At a basic level, a mismatch between the frame rate and refresh rate can cause stuttering (VSync on) or tearing and juddering (VSync off). Dimensions: 21.9 x 20.7 x 9.9 inches. Brighter elements stood out well against darker surroundings and the detail levels for most of the screen were appropriate. Such an option does usually exist it may be called sync every frame or something along those lines rather than simply VSync. The images below show the refresh rates available in the native Full HD resolution. The darkest blue block blended into the background a bit too readily. While cinematic first-person games really benefit from large, high-res displays, online multiplayer games like Overwatch and Counter-Strike: Global Offensive really shine with high refresh rates. Styling is minimalist but distinctly Alienware. With the AW2521HF, you need to connect the monitor up via DisplayPort and enable FreeSync in the Game section of the OSD. The setting is listed as Wait for Vertical Refresh. As of driver version 417.71, users with Nvidia GPUs (GTX 10 series and newer) and Windows 10 can also make use of this Variable Refresh Rate (VRR) technology. These were briefly explored in the OSD video, but for the purposes of this table well be looking at manual adjustments and settings we feel have more utility. Brightness can be raised to compensate. This is most noticeable towards the bottom corners of the screen, from a normal viewing position. It doesnt show strong graininess or a heavily smeared appearance, however. Not to the extent seen on models with a more generous colour gamut, but enough to stand out and have the intended look overall. The consistency is also very good in most cases, superior to VA models and far superior to TN models (references here). Most pixel transitions were performed fast enough for a solid 240Hz experience, with either no additional trailing or just a little light powdery trailing in places. FreeSync requires a compatible AMD GPU such as the Radeon RX 580 used in our test system. There is a little light powdery trailing behind the UFOs, particularly for the dark and medium backgrounds. The AW2521HF supports FreeSync Premium via DP 1.2a and HDMI 2.0 on compatible GPUs and systems. Responsiveness (Adaptive-Sync). In contrast to models with G-SYNC modules, which feature variable overdrive that re-tunes things dynamically to a wide range of different refresh rates. Press OK, then turn the monitor off then on again so that it re-establishes connection the technology should now be active. If you activate the Frame Rate feature under Game Game Enhance Mode in the OSD, this will display the refresh rate of the display and therefore indicate the frame rate if FreeSync is active and the frame rate is within the variable refresh rate range of the display. Without FreeSync active and VSync disabled, youd get obvious tearing from the lack of synchronisation between frame and refresh rate. Plus a bit of overextension, in the green to red region. The technology worked well and offered a very similar experience to AMD FreeSync. In the review of the Alienware AW2518H, it says that they calibrated the monitor to offer better colors but i can`t seem to find the exact settings that they used. Either way, where the frame rate drops below the floor of operation a frame to refresh multiplication technology (what AMD refers to as LFC) kicked in to keep tearing and stuttering at bay. Alienware 25 Gaming Monitor AW2521H at Dell for $679.99. VA models have black crush centrally which masks some detail, whilst some excessive detail can be observed towards the bottom and side edges from a normal viewing position. The display is bezel-free on three sides, but you will still see thin panel borders when the display is in use. Classic and satisfying dish with garlic, lemon, and rosemary. Sensitivity to such things varies, however. Note that if the monitor is running at a refresh rate from the first list, including 60Hz, steps must be taken to correct the colour signal on Nvidia GPUs. Together, the monitor certainly didnt provide a deep and atmospheric look to dark scenes and is more suited to viewing in a well-lit room. We observed some faint vertical dynamic interlace patterns at ~60Hz and below, but these were not particularly obtrusive in our view. The connected feel and perceived blur took a real hit here, but the technology did its thing to get rid of tearing and stuttering all the same. Nvidias website lists a 48 240Hz VRR, which would match AMD FreeSync. Shade representation using SpyderCHECKR 24 Our RX 580 is far from a powerhouse of a graphics card, so maintaining 240fps was very tricky. Strong colour consistency and slight extension beyond sRGB, giving a rich and natural image without potentially overbearing saturation Where possible, the monitor dynamically adjusts its refresh rate so that it matches the frame rate being outputted by the GPU. This indicates that the monitor has been specifically tested by Nvidia and passes specific quality checks. The numbered Game presets and Custom Color are most flexible as they allow you to adjust the colour channels and saturation levels. A slight difference was that the floor of operation was 80Hz (80fps) on our Nvidia GPU. The experience wasnt as cinematic as on models with much stronger static contrast, particularly in a dimly lit room. Features and Specifications. The images below are pursuit photographs taken using the UFO Motion Test for ghosting, with the test running at its default speed of 960 pixels per second. In this case appropriate richness and saturation was maintained throughout.
